5 Claims.

This invention relates primarily to mining equipment and more particularly to a conveyerloader for loading mine carswith coal.

It is however to be understood that the con- 5 veyer-loader embodying the features of the present invention is not limited to the use above ascribed and will in actual practice be found equally useful in the handling of granular materials of all kinds.

10 I More specifically the invention has reference to the shaker type of conveyer-loader now generally employed in coal mining operations, and an object of the invention is toprovide improved means for swinging the pivoted intake end of the conveyer-loader; as well as also providing improved means for telescoping the sections of the pivoted intake end of the conveyer-loader.

Other objects and advantages of the invention will be understood from a study of the following description taken in connection with the accompanying drawings wherein is illustrated a preferred embodiment of the invention.

In the drawings:

Figure 1 is a top plan view of a conveyer-loader 25 embodying the features of the present invention.

Figure 2 is a side elevational' view thereof.

Figure 3 is a bottom plan View.

Figures 4, 5, 6, 7, 8, and 9 are sectional views taken substantially on the lines 4-4, 5-5, 6-45,

30 L4, 88 and 9-9 respectively of Figure 1.

Figure 10 is a top plan View of the mechanisms for extending and retracting the pivoted intake end of the loader and also the mechanism for laterally swinging said loader end.

35 Figures 11, 12 and 13 are sectional views taken substantially on the lines II-I I, I2--I2 and i3I3 respectively of Figure 10.

Figure 14 is a perspective view of one end of the sliding section of the intake end of the conveyer- 40 "loader, and V Figure 15 is a fragmentary sectional elevational view illustrating certain details of a device for securing the section of the pivoted intake end of the conveyer-loader in fixed position relative to 45 one another, and to be hereinafter more fully referred to.

Referring to the drawings by reference numerals it will be seen that 5 indicates generally one end portion of a conventional type'of reciprocating or shaker conveyer-loader now generally employed in coal mining operation for conveying and loading coal. As is well known at the intake end thereof such conveyer-loader has a pivoted part that is usually longitudinally extensible and is forced into the material in the operation of placing the material on the conveyerloader to be carried thereby 'totheimine cars. At said end the conveyer 5 is provided with a fixed flare mouth structure 6 to which is pivoted the intake end I of the conveyer.

In accordance with the present invention the conveyer end I includes an outer section 8 and an inner slidable section 9. At one end thereof the section 8 is pivoted to the mouth 6 of the conveyer 5 for swinging movement towards the right 5 and left.

The present invention includes an improved connection between the conveyer section 8 and the mouth 6, said connection comprising a substantially U-shaped yoke II] formed from a metal 10 rod of suitable length and strength. The yoke II] has the sides thereof, at the open end of the yoke secured by headed studs or similar fastening elements II to lugs I2 provided on the under side of the conveyer section 8. Between the ends 15 thereof the yoke It! operates in suitable guides I3 properly positioned and secured to the under side of the mouth 6 all of which will be clear from a study of Figures 3 and 4.

The sections 8 and 9 have their upstanding sides provided with flanges I4, I5, the flanges I5 of the sliding section 9 overlapping the flanges I4 of the swinging section 8. At its inner end sliding section 9 has integral with its flanges IS a strap I 9 that has its intermediate portion in sliding contact with the under face of the bottom of the swinging section 8 whereby provision is made for retaining the sections 8, 9 in assembled relation and for sliding movement of the section 9 relative to the section 8. (See Figures 3 and 9.)

At its outer or free end sliding section 9 has portions of its sides removed to provide a tongue I'I. Associated with the tongue or outer end of the sliding section 9 is a head or shovel indicated generally by the reference numeral I8.

The improved head I8 comprises a broad substantially flat plate I9 having at its rear oblique edges 20 merging with the side edges of a reduced portion or shank 2| that has rising from opposite edges thereof sides 22, said sides having integral 40 extensions 23 continuing therefrom along the edges 29 of the plate I9 and integral at said edges 29 with the plate. The sides 22 accommodate therebetween the flange-less end portion of the sides of section 9, and said sides 22 have their upper portions cut away to accommodate rods 24 a suitably mounted thereon. Rods 24 are accommodated in the apertures of lugs 25 provided on the aforementioned portion of the sides of the sliding section 9 whereby a connection is formed between the section 9 and the shovel for limited relative movement between these parts. For cushioning purposes springs 26 are suitably provided on the rods 24, one adjacent each end of each of the rods as shown in Figure 1. On the top side or face thereof there is suitably secured to the body plate I9 of the shovel I8spaced plates 21' and the plate I9 and plates 21 are mutually separated at the inner confronting edges of the platesZ'I for accommodating in a slidable manner the tongue I? of the section 9 as will be clear from a study of Figures 1, and 6.

A salient feature of the present invention is the provision of a base member 28 located beneath the mouth equipped end of the chute 5. In the present instance the base 28 is in the form of a frame provided at the ends thereof with bearings 29, and intermediate said ends with relatively spaced transverse bearing plates 3!). J ournalled in the bearings is a shaft 3| For swinging the pivoted intake end of the chute laterally there are mounted on the ends of the shaft 3| drums 32, 33 which are loose on the shaft. Drums 32, 33 have windable thereon cables 34, 35 and these cables at one end are secured as at 36 to the side extensions 23 of shovel I8 as shown in Figure l. The cables 34, 35 extend through suitable apertures provided therefor in the front side of the frame or base 23 and at opposite sides of the pivoted ends of the. conveyer, rearwardly of the shovel are trained over pulleys 38 mounted on suitable posts or similar anchors 39. It will thus be seen that by placing one of the drums in driving connection with the shaft 3| the cable associated with said drum will be wound thereon, and the other of the drums being loose on the shaft a swinging of the intake end of the conveyer-loader in one lateral direction will be accomplished.

Means is provided for utilizing the reciprocatory movement of the conveyer 5 for driving the shaft 3|, and in the present instance such means comprises rack bars 46 mounted on the sides of the conveyer 5 and meshing with rack gears 4| loose on the shaft 3|. Secured to the shaft 3| for rotation therewith are ratchet wheels 32 arranged on the shaft 3| relative to the drums 3 2, 33 and the gears 4|, as clearly shown in Figure 8. Carried by the gears 4| are pivoted dogs 43 engageable with the ratchet wheels 42 upon rotation of the wheels 4| in one direction for transmitting movement of the wheels 4| to the shaft 3|.

For placing the drums 32, 33 in driving engagement with the shaft 3| there is provided on one end of each drum a clutch member 44 with which is 'cooperable clutch member 45 slidably mounted on the shaft 3|. For simultaneously operating the clutches 45 there are engaged with said clutch members 45 yokes 46 pivoted as at 41 to the base 23. Yokes 46 are pivotally connected by a link 48, which link, at one end is pivoted to an operating lever 49 pivotally mounted on the base 28. In Figure the position of the lever 49 is neutral. Obviously by rocking the lever in one direction, for example in a clockwise direction, clutch elements A l, 45 associated with the drum 32 will be engaged when the drum 32 is in driving engagement with the shaft 3| while the clutch element associated with the drum 33 will remain disengaged leaving the drum 33 idle on the shaft.

To swing the pivoted intake end of the conveyer laterally in one direction, for example, in an anti-clockwise direction clutch element 44, 45 associated with the drum 32 is engaged so that as the shaft 3| rotates in a clockwise direction drum' 32 will rotate therewith for winding the cable 34 on said drum while drum 33 will be free on the shaft permitting a paying out of the cable 35. Obviously the winding up of the cable 34 on .its drum 32 will thus cause the intake end of the conveyer to swing in the direction above indiposition is desired, and on the return stroke the shovel is of course forced into the pile of material for scooping therefrom sufficient material to be conveyed by the conveyer to the cars being loaded. To return the intake end of the conveyer to its normal position or the position shown in Figure 1 obviously a reverse of the operation above described is resorted to, that is to say lever 49 is swung in an anti-clockwise direction to release the drive connection between shaft 3! and drum 32 and to operate the clutch element associated with drum 33 for placing the drum 33 in driving engagement with the shaft 3| whereupon cable 35 will be wound on its drum for causing the pivoted intake end of the conveyer toswing in a clockwise direction to the position shown in Figure 1.

For sliding the section 9 relative to the section 8 for extending or retracting the pivoted intake end of the conveyer thereare provided on the shaft 3| between the bearing plates 36 a pair of drums 56 on which are windable cables 5|, 52 respectively. Cables 5|, 52 are secured at one end to a lug 53 provided on the aforementioned straps |6 associated with the sliding conveyer section 9. The cable 52 is also trained over a pulley 54 suitably mounted in a bracket provided on the under side of the swinging section 8 adjacent the free end of said section. At the confronting ends thereof the drums 50 are provided with suitable clutch elements 55 with which is selectively engaged at double faced clutch element 56 that is splined to the shaft 3| for rotation with the shaft. For shifting the clutch element 56 there is provided a fork 51 that is engaged with the element 56 and pivoted to the base 28. At its free end the fork 51 is pivotally connected with one end of an operating rod 58 that extends to one side of the conveyer and operates within a suitable guide bracket 59 located in proximity to the handle 49. (See Figure 10.)

From the above it will be seen that to project the pivoted end of the chute, or in other words to slide the section 9 outwardly in the direction of the piled material lever 58 is manipulated to engage the clutch member 56 with the clutch associated with that drum 50 upon which the cable 52 is windable. Thus said drum is placed in driving connection with the shaft 3| for winding the cable 52 on said drum and thereby project the section 3 relative to the section 8. To retract the section 9 clutch member 56 is engaged with the clutch member 55 associated with that drum upon which the cable 5| is windable, thus placing the last named drum in driving engagement with shaft 3| for winding the cable on the last named drum and thus exert a pull on the sliding section 9 for drawing the same inwardly relative to the section 8.

In order to hold the drums 56 against casual rotation a resistance is at all times offered to the drum 53, through the medium, in the present instance, of a suitable device comprising a fork 66 which has the prongs thereof curved as at 6| to peripherally engage the drums 50 in a manner shown in Figures 10 and 12. The shank of the fork 60 extends through an opening in one side of the base 28 and is equipped with a lock nut 62 for securing the fork 60 at the desired adjustment.

The invention further comprehends the provision of simple and inexpensive means securing the sliding section 9 at the desired adjustment relative to the swinging section 8, and in the present instance such means comprises cams 63 mounted on suitable lugs provided at opposite sides of the swinging section 8. The cams 63 are provided with levers 64 pivotally connected by links 65 with crank arms 66 fixed on a transverse shaft 61 in bearings 88 provided at the under side of the swinging section 8. For rocking the shaft 61 there is provided an arm 69 on said shaft and pivotally connected with the arm 69 is a rod or link 18 that is also pivotally connected to an operating lever H pivotally mounted on one side of the section 8. A spring 12 is suitably anchored at one end to the section 8 and has its other end suitably connected with the lever H for normally urging the lever to rotate in a clockwise direction and thereby maintain earns 63 in engagement with the flanges I5 on the section 9 to urge said flanges l5 into intimate contact with the flanges l4 of the sections 8 to thereby frictionally retain the sections 8 and S at the desired adjustment relative to one another. tion 9 relative to section 8 the lever II is first swung in an anti-clockwise direction against the action of spring 12 for releasing the cam 63 and thereby free the section 9. A sliding of the section 9 can then be readily accomplished by engaging in a manner hereinbefore explained in detail clutch element 55 with the clutch element 55 associated with the proper drum 50.

From the above detailed description it will be apparent that in accordance with this invention a simple mechanism is provided for swinging the intake end of a shaker or reciprocating conveyerloader, and a mechanism of simple construction and of efficient operation is provided for extending or retracting said pivoted intake end of the conveyer-loader and that also the reciprocatory movement of the conveyer is utilized in an effective and efiicient manner for driving the drum supporting shaft, which shaft in turn is common to the two mechanisms above set out. Thus provision is made for the control of the pivoted end of the conveyer-loader by a single operator while at the same time a mechanical swinging of the intake end of the conveyer-loader is accomplished whereas, at the present time a crowbar is necessary with the conveyers now in use for swinging the intake end thereof to one side or the other and back to neutral or normal position.

If desired any suitable means may be provided for holding the head or shovel l8 rigid relative to the sliding section 9 of the feeder or intake end of the conveyer-loader, and in the present instance such means, in its simplest form, is illustrated as embodying a screw 13 engaged with one of the lugs and adapted to be threaded into engagement with a rod 24 to bind the rod and thereby prevent relative movement of the section 9 and head or shovel l8.
